PCV Valve
Perhaps this is a silly question,
But I am wondering when others have/intend on changing their PCV valve? I've gone over the scheduled maintenance but do not see it listed. I have 79k on my '10 350.

i check my oil regularly and let oil consumption be the gauge to let me know when to change my PCV. Any noticed increase of oil usage usually points out to me that the PCV might be stuck.

On top of the engine, I think over toward the driver side. I think you need to pull the plastic cover off to see it. Takes 1 minute to change. I did it last year.
See this for the Highlander, should be the same. There is a photo halfway down

How to check Your car PCV valve !!!
Take it out, clean it with CRC valve cleaner and then shake it up and down. You should hear the movent piston inside.
After that blow and suck air in one side. air should flow from the engine top towards the intake manifold. If it does return the valve back with a little Teflon around the screw in part. Now you are good to go for another 30,000 miles !

Furthermore, it is a $6-$10 part that have to be removed off the engine for cleaning anyway, so just put a new PCV valve on the engine instead of reusing a part that has been used for years.
Cleaning an old PCV valve is like stitching up old underwear with holes to avoid buying a new pack for about $10.
